of the pump can be above 60°C / 140°F.
Under these conditions the pump must be
labelled with a “Danger Hot” sign.
When using an electric motor, the motor must
always be supplied with adequate cooling
ventilation.
When using an electric motor together with a
VFD (Variable Frequency Drive), the motor must
be designed for operation with VFD. VFD
operation may increase the temperature inside
the electric motor if the motor is not designed
for VFD operation. This can damage the motor
and cause unintended breakdown.
Before start-up, the settings for all protective
devices, such as sensors/switches and safety
valves must be verified and free flow from safety
valves must be ensured.
All pipe and hose connections must be stressfree mounted, securely fastened to the pump
and well supported. Improper installation will or
could result in personal injury and/or damage to
the pump.
Use of this manual does not relieve operation
and maintenance personnel of the responsibility of applying good judgment when operating
and maintaining the pump and its components.

3.7Filtration
(10µm absolute [β10 ≥ 5000])
Requirements are specified in appendix 1, Data
sheet and appendix 2, Instruction.
Danfoss recommends not to build a filter bypass
function or use filters with an integrated bypass.
If the above recommendation is not followed the
warranty for the pump will automatically
become void.
It should be possible to monitor the condition of
the filter via the differential/delta pressure across
the filter.
Using insufficient filtration or a filter bypass
can cause a failure or decreased service life of
the pump.
3.9 Air bubbles
Large bubbles in a pressurised system can result
in damage to piping, equipment and the pump.
All air must be bleeded from both the low-­
pressure and high-pressure side before the
system is pressurised. Special consideration
should be given in order to minimize air bubbles
in the feed flow. Air bubbles can cause cavitation.
3.10Chemicals
The pumps should not be exposed to any
chemicals that can result in damage to piping,
equipment and internal parts of the pump.
3.8 Properties of water
It is recommended NOT to use the pump for
other media than specified in the Data sheet.

transportation,
handling, lifting and
storage
4.1 Arrival inspection
The pump is packed in a cardboard or wood box
with plugs in the port connections to protect the
pump from damage during transportation.
When the shipment has arrived it is important to
check the pump for any damages. The name
plate/type designation must be in accordance
with the delivery note and your order.
4.4 Transport and handling
Small pumps which have a weight below 20 kilos
(weight can be found in appendix 1, Data sheet)
can be handled by hand if they are not mounted
together with an electric motor. The weight of a
small pump with a motor will be above 20 kilos.
In case of damage and/or missing parts, a report
should be documented and presented to the
carrier at once.
4.2Warning

Introduction
The Danfoss range of PAHT and PAHT G highpressure pumps is specifically designed for use
with technical water such as:
•
•
•
Ultra-pure water that has undergone
multiple reverse osmosis processes
De-ionized water
Demineralized water
Danfoss PAHT pumps are positive displacement
pumps, with axial pistons that move a fixed
amount of water in each cycle. Flow is proportional to the number of input shaft revolutions
(rpm). Unlike centrifugal pumps, they produce
the same flow at a given speed no matter what
the discharge pressure.

/ 05.2013
The range of PAHT G pumps is based on the
standard PAHT pump series. The PAHT G pumps
are made with some extra coatings that reduce
the wear of the pump. This coating is particularly
important for pumps used in gas turbine
applications or other similar applications where
the wear of the pumps is high due to the ultra
pure water quality.
The next pages will cover both PAHT and PAHT G
pumps with the name PAHT pumps.

ero risk of lubricant contamination:
- Oil lubricants are replaced with the
pumped medium, water, so there is no
contamination risk from the pump.
Low maintenance costs:
- Efficient design and all-stainless steel
construction ensure exceptionally long
life. When Danfoss specifications are
met, service intervals of up to 8,000
hours can be expected. Service is easy,
and can be carried out on site due to
the simple design and few parts.
Low energy costs:
- The highly efficient axial piston design
provides the lowest electricity consumption of any comparable pump on
the market.
Easy installation:
- The lightest and most compact design
available.
High-pressure cleaning with ultra-pure
water, as used in the manufacturing of
flat-panel displays and other electronic
products.
High-pressure cleaning with ultra-pure
water, as used in the manufacturing of
parts for the automobile industry.
Adiabatic cooling systems to replace or
supplement standard A/C systems in server
rooms and factories.

Flow
Q eff = Q (th) – [(Q (th) – Q (p max)) x (p / p max)]
The theoretical flow can be calculated with the
following equation:

7.1 Filtration
Proper filtration is crucial for the performance,
maintenance and warranty of your pump.
Protect your pump, and the application in which
it is installed, by always ensuring that all filtration
specifications are met, and by always changing
filter cartridges according to schedule.
Since water has very low viscosity, Danfoss PAHT
pumps have been designed with very narrow
clearances in order to control internal leakage
rates and improve component performance. To
minimize wear on the pump, it is therefore
essential to filter inlet water properly.
The main filter must have a filtration efficiency
of 99.98% at 10 μm. We strongly recommend
that you always use precision depth filter
cartridges rated 10 μm abs. β10 ≥ 5000.
Please note that we do not recommend bag
filters or string-wound filter cartridges, which
typically have only 50% filtration efficiency. This
means that out of 100,000 particles that enter
such filters, 50,000 particles pass right through
them; compare this to precision depth filters that
are 99.98% efficient, and only allow 20 of the
same 100,000 particles to pass through.

For more information on the importance of
proper filtration, including explanation of
filtration principles, definitions, and guidance on
how to select the right filter for your pump,
please consult our Filtration information and
specifications (Danfoss document number
521B1009).
7.2 Noise
Since the pump unit is mounted on a frame, the
overall noise level can only be determined for a
complete system. To minimize vibrations and
noise throughout the system, it is therefore very
important to mount the pump unit correctly on a
frame with dampers and to use flexible hoses
rather than metal pipes where possible.
The noise level is influenced by:
•
Pump speed:
High rpm makes more fluid/structureborne pulsations/vibrations than low rpm.
•
Discharge pressure:
High pressure makes more noise than low
pressure.
•
Pump mounting:
Rigid mounting makes more noise than
flexible mounting because of structureborne vibrations. Be sure to use dampers
when mounting.
•
Connections to pump:
Pipes connected directly to the pump make
more noise than flexible hoses because of
structure-borne vibrations.
•
Variable frequency drives (VFDs):
Motors regulated by VFDs can produce
more noise if the VFD does not have the
right settings.

Inlet line:
Dimension the inlet line to obtain minimum pressure loss (large flow, minimum
pipe length, minimum number of bends/
connections, and fittings with small
pressure losses).
Inlet filter:
Install the inlet filter (1) in front of the PAHT
pump (2). Please consult the Danfoss filter
data sheet for guidance on how to select
the right filter.
Monitoring pressure switch:
Install the monitoring pressure switch (3)
between the filter and the pump inlet. Set
the minimum inlet pressure according to

data. The monitoring pressure switch stops
the pump if inlet pressure is lower than the
set minimum pressure.
Monitoring temperature switch:
Install the monitoring temperature switch
(4) between the filter and the pump, on
either side of the monitoring pressure
switch. Set the temperature value according to technical data, item 4. The monitoring temperature switch stops the pump if
inlet temperature is higher than the set
value.

Danfoss PAHT pumps are designed for long
periods of service-free operation to provide
customers with low maintenance and life cycle
costs. Provided that the pump is installed and
operated according to Danfoss specifications,
Danfoss PAHT pumps typically run 8,000 hours
between service routines. However, the service
schedule for your Danfoss PAHT pump may vary
according to the application and other factors.
Service
The life of a pump may be greatly shortened if
Danfoss recommendations concerning system
design and operation are not followed.
In our experience, poor filtration is the number
one cause of pump damage.
Other factors that affect pump performance and
lifetime include:
•
•
•
•
running the pump at speeds outside
specifications
supplying the pump with water at temperatures higher than recommended
running the pump at inlet pressures
outside specifications
running the pump at outlet pressures
outside the specifications.
We recommend that you inspect your pump
after 8,000 hours of operation even if it is
running without any noticeable problems.
Replace any worn parts as necessary, including
pistons and shaft seals, to keep your pump
running efficiently and to prevent breakdown. If
worn parts are not replaced, then our guidelines
recommend more frequent inspection.

System design
Systems can be either:
•
•
•
Water hydraulic systems, in which the water
is recirculated back to tank.
Open-ended systems with water supply
from a tank.
Open-ended systems with direct watersupply (boosted pressure).
The design of the system must ensure that
selfemptying of the pump during standstill is
avoided.
The minimum boost pressure is 2 barg (29 psig)
and the maximum peak pressure is 20 barg
(290 psig). The recommended normal boost
pressure is 2-6 barg (29-87 psig) (3-7 barg
[43.5-101.5 psig] abs).
If it is unknown what the peak inlet pressure can
be, then there should be a 15 barg (218 psig)
safety relief valve on the inlet side of the pump.
Note: All mentioned pressures refer to
measures in the respective pump gauge ports.
The inlet pressure of the pump must never
exceed the outlet pressure. This may typically
occur in boosted or open-ended systems with
supply direct from the tap and where a bypass
valve is activated.
Closed water hydraulic systems, water
recirculated
(The numbers 1- 3 refer to the drawing below ).
In order to eliminate the risk of cavitation, always
ensure a minimum inlet pressure of 0 barg
(0 psig) (1 barg [14.5 psig] abs) by observing the
following guidelines:
2.2 Open-ended systems, water supply from

(The numbers 1-3 refer to the drawing below ).
In order to eliminate the risk of cavitation, always
ensure a minimum inlet pressure of 0 barg
(0 psig) (1 barg (14.5 psig) abs) by observing the
following guidelines:
1)
Place the tank above the pump (water level
in the tank should always be above the
pump).
2)
Place the inlet filter before the tank.
3)
Dimension the inlet line to obtain minimum pressure loss (large flow area,
minimum pipe length, minimum number
of bends/connections, fittings with small
pressure losses).
2.1
1)
Place the tank above pump and pump inlet.
2)
Place the main filter in the return line and
not in the suction line.
3)
Dimension the inlet line with a minimum
pressure loss (large flow area, minimum
length of pipe, minimum number of bends/
connections, fittings with small pressure
losses).

Filtration
A good filtration is vital to ensure a long and
trouble free life of the pump.
When selecting a filter or strainer, please note
that filter materials should be compatible with
water, i.e. should neither corrode or dissolve. Also
be aware of the electrochemical series of the
applied materials.
•
•
Pump suction line should be placed relatively
high above the tank bottom in order to prevent
settled particles from being led into the pump.
We recommend a separation (“wall”) to separate
the inlet from the outlet end of the tank.
Main filter must have a fineness of 10 µm
abs. β10 >5000.
In
The pressure loss across the filter should be
monitored.
Please contact Danfoss High Pressure Pumps for
further filter details.
Water tank
Must be made of corrosion-proof material such
as stainless steel or plastic and must be sealed to
prevent entrance of impurities from the environment.
Automatic pressure equalization between tank
and surroundings must be ensured.
Inlet from the water supply (the return line) and
inlet to the pump should be placed in opposite
ends of the tank to calm and deaerate the water,
and to ensure optimum opportunity for particles
to settle.

Monitoring
It is recommended to continuously monitor the
following conditions:
•
•
•
•
Water level (if a tank is used)
Filter contamination
Pressure (inlet side of the pump)
Temperature (inlet side of the pump)
Please take care to observe the recommended
length tolerances of the chosen coupling, as an
axial force on the pump shaft will prevent the
pump from generating pressure (and over time
damage the pump).

3.3 Orientation
The pump can be mounted/orientated in any
horizontal position and it can be mounted/
orientated in the vertical position with the shaft
upwards. The pump cannot be vertically
mounted/orientated with the shaft facing
downwards.
3.4 Protection from too high system
pressures
The pump should be protected against too high
pressure by means of a pressure relief valve or a
bypass/unloading valve placed on the pressure
side.
The valve should be placed as close to the pump
as possible.
The opening characteristics of the valve must not
result in peak pressures higher than 200 barg
(2,900 psig).

Operation
5.1 Water quality
Water of drinking water quality, confirming to
the EEC directive 98/83/EC and without abrasive
sediments, demineralized water, de-ionised
water, softened water and RO water.
5.3 Pressure
The inlet pressure must be min. 2 barg equals
3 barg abs. At lower pressures the pump run a
risk of cavitating, resulting in damage of the
pump.
Please contact Danfoss High Pressure Pumps
sales organization in case of doubt.
Short term inlet pressure peaks must not exceed
20 barg (290 psig). It is recommended that the
normal boost pressure is 2-6 barg (29-87 psig)
(3-7 barg [43.5-101.5 psig] abs).
5.2 Temperature
Fluid temperature:
Min. +3° C / 37,4° F to max. +50° C / 122° F
If it is unknown what the peak inlet pressure can
be, then there should be a 15 barg (218 psig)
safety relief valve on the inlet side of the pump.
Ambient temperature:
Min. 0° C / 32° F to max. 50° C / 122° F
Max. pressure on the pump’s outlet line should
be limited at 160 barg (2,320 psig) continuously.
Storage temperature:
Min. -40° C / -40° F to max. +70° C / 158° F
Short-term pressure peaks (e.g. in connection
with closing of a valve) of up to 200 barg
(2,900 psig) are acceptable.
To protect the pump from too high fluid
temperature, a temperature switch of 50° C
(122° F) should be mounted on the inlet side. If
the whole pump flow is bypassed over the relief
valve, then the fluid tempe-rature will go up
relatively fast.

It is recommended to have a check valve on the
outlet side of the pump to protect the pump
from high pressure going backwards into the
pump when it is turned off. Especially, when
using flexible hose or more pumps are installed
in the same system.
Instruction
Pump instruction PAHT/PAHT G 20-32 and PAHT/PAHT G 50-90
5.4 Dry running
When running, the pump must always be
connected to the water supply in order to avoid
damage if it should run dry.
In systems with water tank it is recommended to
build in a level gauge in the tank to avoid the risk
of running dry.
In systems with a boost pump, it is strongly
recommended to have a low pressure switch
mounted on the water inlet side set at minimum
2 barg (29 psig).
5.5 Disconnection
If the inlet line is disconnected from the water
supply, the pump will be emptied of water
through the disconnected inlet line. When
starting up again, follow the bleeding procedure
described under section 4: Initial start up.
5.6 Storage
When preparing the pump for long-term storage
or for temperatures below the freezing point,
flush the pump with an anti-freeze medium type
monopropylene glycol to prevent internal
corrosion or frost in the pump.
For further information on anti-freeze media,
please contact the Danfoss High Pressure Pumps
sales organization.
Recommended procedure:
5.6.1 Water hydraulic systems, water recirculated
1.
Disconnect the power pack from the
system.
2.
Empty the tank of water. Fill up the tank
with anti-freeze medium to a level well
above the suction line.
3.
Start up the power pack and, for a couple
of minutes, in a closed loop system let the
anti-freeze medium run back to tank
through the pressure relief valve or the
bypass valve.
6.
Service
The Danfoss PAHT/PAHT G pumps are designed
for long periods of service-free operation to
provide customers with low maintenance and
life cycle costs. Provided that the pumps are
installed and operated according to Danfoss
specifications, the Danfoss PAHT/PAHT G pumps
typically run 8,000 hours between service
routines. However, the service schedule for your
PAHT/PAHT G pump may vary according to the
application and other factors.
The life of a pump may be greatly shortened if
Danfoss recommendations concerning system
design and operation are not followed.
4.
Empty the tank of the anti-freeze medium.
Empty the pump through the lower
bleeding plug.
The pump is now protected against internal
corrosion and frost.
5.6.2 Open-ended systems with water supply
from tank.
1.
Empty the tank of water and empty the
pump housing through the lower bleeding
plug. When the pump is empty, retighten
the plug.
2.
Through the upper bleeding plug, fill the
pump housing with anti-freeze medium.
Pour anti-freeze medium into the tank.
Connect a hose to the outlet of the pump
and lead the other end of the hose back to
tank.
3.
Quickly start and stop the pump. Make
sure that the pump does not run dry.
The pump is now protected against internal
corrosion and frost.
5.6.3 Open-ended systems with direct water
supply.
1.
Disconnect the water supply to the pump.
2.
Through the lower bleeding plug, empty
the pump housing of water and close it
again.
3.
Connect the pump to a tank of eg. 25 litre
(6 gal.) of anti-freeze additive. Connect a
hose to the inlet port of the pump and via
another hose return the flow from the
outlet port port to the tank with anti-freeze
additives.
4.
Quickly start and stop the pump. Make
sure that the pump does not run dry.
The pump is now protected against internal
corrosion and frost.
Other factors that affect pump performance and
lifetime include:
•
•
•
•
running the pump at speeds outside
specifications
supplying the pump with water at temperatures higher than recommended
running the pump at inlet pressures
outside specifications
running the pump at outlet pressures
outside the specifications.
In our experience, poor filtration is the number
one cause of pump damage.

7.1 General information
This guideline provides information on the
recommended service intervals for the PAHT/
PAHT G pumps. The recommendation is based
upon good engineering practice and on
experience gained from operation even under
extreme conditions.
Recommended service
intervals
The recommendation is for guidance only.
7.2 Inspection of pump parts
Danfoss recommends to inspect the pumps after
8,000 hours. Typical signs of wear are seen on the
contact/sliding surfaces in the pumps. If the
pumps must run for additional 8,000 hours, the
following parts will have to be inspected:
•
•
•
•
•
Pistons
Retainer plate, ball and bearing
Valve plate
Port plate
Sealings
If service inspection due to the application is
complicated, the plant operator can decide to
extend the service interval by evaluating the
following deviations:
•
•
•
Sound - does the pump have any unusual
sounds?
Electric motor power consumption and
speed compared with measurement made
in the past.
Pressure/flow according to measurements
made in the past?
We advise that the above mentioned parameter
during the extended service interval is inspected
for every 500-2,000 hours beyond the 8,000
hours. The pump must in any case be inspected
after maximum 16,000 hours or 2 years.
7.3 How to inspect the pump
Service manuals are available on the internet
www.danfoss.high-pressurepumps.com
If there are any wear marks on the parts they
need to be replaced.

Motor Manual
Bearing size and type are specified on the rating plate.
Motor types HMA2 and HMC2 is as standard with lifetime
greased bearing with motor size ≤225.
Motor types MS and Y2E is as standard with lifetime greased
bearing with motor size ≤160.
The table values are based on an ambient temperature of
25°C. The values must be halved for every 15K increase in
bearing temperature.
Higher speed operations, e.g. frequency converter drive will
require shorter greasing intervals. Typically, doubling the
speed will reduce the values by 50%.

Motors with a re-greasing system must be lubricated with
high quality lithium complex grease, NLGI grade 2 or 3, with
a temperature range of between -40°C to +150°C.
Motors are normal fitted with a data plate with greasing
information; if it is missing use the following re-greasing
intervals.

Grease the motor while running, open the grease outlet plug
and let the motor run 1-2 hours before the outlet grease
plug is closed again.
Grease the motor for the first time during commissioning.
The following applies in general for both lifetime lubricated
and re-lubricated bearings:
At 60Hz the time will be reduced by app. 20%.
Data for vertically mounted motors are half of the above
values.
The dust hazardous 3-phase asynchronous motors are
in accordance with European standard EN 50281-1-1.
Combustible dust areas will be found in agricultural areas
and in industrial environments.
Only one electrical installation may be installed in one
specified area (zone).
Only certificated cable glands for category 2D may be used.
Unused glands must be closed.
Connections must be made in such a way as to ensure that
a permanently safe electrical connection is maintained,
both for the main supply and earth connection.
Installations must be in accordance with actual standards
for installation in the Zone 22 area.
It is recommended that EN 50281-2 is followed according
temperature and dust on the motor surface.
The use of motors with so much surface dust that the
motor temperature increases is not permitted.
Regularly cleaning is recommended.
The radial shaft sealing ring is part of the ATEX certification.
It is important that the ring is always intact.
The shaft sealing must be regularly checked, and if dry
it must be lubricated. It is recommended that the seal is
re-lubricated regularly.
Always use the original seal ring when replaced.
Replacing bearings also means replacing the seals.
All machines must be inspected regularly for mechanical
damage.
The user is responsible for changing parts in accordance
with the lifetime of parts, in particular:
bearings, grease and lubrication of shaft sealing.
Maintenance, repairs and replacement on zone 22 motors
must only be carried out by qualified specialists.

Rotation direction for the pump is shown by an
arrow on the label on the pump.
WARNING:
- The pump must not run without water for
more than a few seconds.
- If the pump takes in water from the highpressure outlet line, it builds up pressure in
pump housing and will eventually break
down.

Reduced flow/reduced pressure
Cause
Remedy
Comments
2.1 Wear on pump
Large internal leakage due to:
2.1.1 Dismantle the pump.
2.1.2 Check valve plate.
Valve plate has marks/scratches on the
surface facing the port plate. Minor wear
on valve plate can cause large internal
leakage. See Index 6.1.
2.1.3 Check port plate.
Port plate has marks/scratches on the
surface facing the valve plate. Minor wear
on port plate can cause large internal
leakage. See Index 6.2.
2.1.4 Check cylinder barrel.
Liners in cylinder barrel may be scratched
or worn. Insert a piston in the liner and
check the fit. If there is any space
(clearance) between liner and piston, liner
or piston is worn.
2.1.5 Pre-treatment:
Analyse fluid for content of particles.
- Check that filters are OK and working
correctly.
2.1.6 Main filtration:
Check that the correct filter type is used
(particles in fluidmust not exceed 10 μm).
Danfoss High Pressure Pumps supplies
filters, please contact the sales office.
Typical signs of wear:
Polished surface all over the swash plate.
Normally, only half of the swash plate = the
pressure side is polished. See index 6.3.
2.1.7 Fluid type:
The PAH/PAH F (tapwater) and PAHT/PAHT
G (ultra pure water) pumps are designed
for water operation; for any other fluid,
please contact Danfoss High Pressure
Pumps sales office for further help.
Insufficient filtration means that too many or
too large hard particles can pass the main filter
because it is damaged, bypassed or simply too
poor. Filtration efficiency must be 99.98%
(Beta = 5000) at 10 μm to prevent abnormal
wear of the pump.
2.1.8 High fluid temperature:
If fluid temperature is above 50°C, stop the
pump immediately.
Temperature > 50° C will cause wear on internal
pump parts. Mount a temperature switch and
check its set point / function. The temperature
switch will ensure that the pump stops at fluid
temperatures > 50° C.
- Check internal parts (see above).
2.2 Low inlet pressure
2.2.1 Check that booster pump supplies the
right pressure/flow.
2.2.2 Check if filters require replacement.
If the ring is missing, the piston is very worn.
The filters can be bypassed, even if they are
correctly mounted. Some filters can create
channelling where particles can pass trough the
filter in tunnels. String wound filters are
typically channelling filters. A string wound
filter may have a filtration efficiency of only
50%, which will cause internal wear and must
always be followed by a main filter.
If the pressure drop across the filters is too high,
the booster pump does not deliver sufficient
flow/pressure. No pressure or low pressure
results in cavitation and insufficient internal
lubrication causing wear on internal pump
parts.
Mount a low-pressure switch in front of the
pump and check its set point/ function. The
low-pressure switch ensures that the pump
does not start until the inlet pressure has
reached 1 bar.
2.3 Rotation speed (rpm)
2.3.1 If VFD-operated, check frequency.
2.3.2 Check that rotation speed of the electric
motor is as stated on name plate on
electric motor. Check that the motor rotor
winding is not damaged.
180R9288 / IOM PAHT/PAHT G 20-90 pumps - v01 / 05.2013

Cause
Remedy
Comments
3.1 Too high outlet pressure from pump
3.1.1 Check for blocked nozzles or a faulty
adjusted relief valve.
Pressure changes due to flow restrictions. This
will also cause high motor torque.
3.2 Pump starts against pressure
3.2.1 Check that electric motor is correctly sized.
3.2.2 Check internal parts (see item 2.1).
3.2.3 Systems with more than one electric
motor installed:
Start motors simultaneously.
Pumps run in parallel with cascade start, may
switch off the motor relay due to too high
torque caused by high outlet pressure.
3.3 Constant torque
3.3.1 Please contact Danfoss sales office.
If the electric motor is too small for the pump, it
cannot provide sufficient torque.
3.4 Water pump damage
3.4.1 Dismantle pump and check for wear.
Too heavy damage in the pump will increase
friction causing a high torque (see item 6,
Typical signs of wear).

Comments
4.1 Air in fluid
4.1.1 Ensure that the entire inlet line is bled
before starting up the system.
4.1.2 Ensure that air cannot enter into the inlet
line.
Small air bubbles will accumulate and create
large bubbles causing internal cavitation and
thus making the pump very noisy.
4.2.1 Follow the instructions “Initial start-up”
supplied with the new pump.
4.2.2 Ensure that the pump is completely bled
before start-up.
The pump and the inlet line must be completely bled before start-up, otherwise the
pump will cavitate and make high noise.
4.3.1 Ensure that inlet pressure is between
the limits specified in the Data sheet.
4.3.2 Check the pump for internal damage.
Too high inlet pressure causes too high
pressure inside the pump damaging the pistons
and eventually the pump.
4.2 Bleeding conditions of pump
4.3 Min/max nominal inlet pressure
WARNING:
The pump can only run few minutes with air in
the fluid without being damaged.
WARNING:
The pump can only run few minutes with air in
the fluid without being damaged.
Inlet pressure below min. limit causes cavitation
and insufficient internal lubrication resulting in
wear on internal pump parts.
Mount a low-pressure switch in front of the
pump and check its set point/ function. The
low-pressure switch will ensure that the pump
does not start until the minimum inlet pressure
has been reached.
4.4 Pump reversing
4.4.1 Dismantle pump and check if anything is
broken or worn (See “1. No flow”, item 1.2
Pump reversing”).
WARNING:
The pump must not run without water
for more than a few seconds. If the pump
takes in water from the high-pressure
outlet line, it builds up pressure and will
eventually be damaged.
4.5 High rotation speed (rpm)
4.5.1 If electric motor rpm is too high, dismantle
pump and check for damage.
4.5.2 If the rpm is within the specified range of
the pump data sheet and abnormal noise
remains, dismantle pump and check for
damage.
If pump rotates in wrong direction, it will take in
water from the high-pressure outlet line.
Pressure will be built up inside the pump and it
will eventually be damaged.
Higher rpm than specified in the pump data
sheet results in wear of the pistons, i.e. pistons
may be damaged.
High rpm will also increase pressure pulsations
from the pump, and the noise level will
increase.
If rpm is changed, noise frequency will also
change.
4.6 Outlet pressure
4.7 Soft start/stop
4.6.1 If outlet pressure is too low, check set
point of outlet pressure valve.
4.6.2 If outlet pressure is lower than mentioned
in the pump data sheet, please contact
Danfoss High Pressure Pumps technical
support.
4.6.3 If outlet pressure has exceeded its
maximum, check set point of outlet
pressure valve.
4.6.4 Check internal parts for wear/damage.
At too low outlet pressure, the pump will create
higher pressure pulsations and thus make
noise. Too low pressure also causes insufficient
internal lubrication and wear on internal parts.
Pump may eventually be damaged.
4.7.1 Check if noise is normal when the pump is
running at operation speed.
4.7.2 If noise is abnormal at operation speed,
check internal parts (see above).
Noise frequency changes during soft start-up/
stop.

Noise from installation
Cause
Remedy
Comments
5.1 Inlet/outlet connections (hoses/pipes)
5.1.1 Use flexible hoses at inlet/outlet connections.
Non-flexible connections mounted directly on
the frame will cause even small pressure
pulsations from pump and create vibrations in
the system/plant.
5.1.2 Mount the connections to the frame by a
vibration damper mounting plate.
5.2 Length/dimension of inlet/outlet line
5.2.1 Increase pipe diameter and/or reduce the
number of bends.
Too small pipes or too many bends may create
too fast flow/turbulence through the pipes and
thus increase the noise level.
5.3 Hose stiffness
5.3.1 Use a more flexible hose.
Too stiff hoses cannot damp the small pressure
pulsations from the pump, and subsequently
vibrations occur in the system/plant.
5.4 Hoses/pipes mounted directly on frame
5.4.1 Mount the connections to the frame by a
vibration damper mounting plate.
If the hoses are mounted directly on the frame,
the small pressure pulsations from the pump
can be transferred to the frame and the rest of
the system/plant.
5.5 Vibration damper under the electric motor
5.5.1 Mount a vibration damper below the
motor/pump.
When no damper is installed below the electric
motor, vibrations from the motor and pump
may be transferred to the frame and the rest of
the system/plant.

Valve plate
Picture 1
A normally worn valve plate has no marks/scratches but only a slightly
polished surface.
No scratches or marks should be felt. The surface must be flat and level.
Picture 2
A worn valve plate has scratches, and/or a polished surface. Even small
scratches will give a loss of flow.
Scratches
Picture 3
A good way to identify a worn valve plate is to hold a straight knife edge
over the valve plate. When holding it up to the light, it will be possible to
see any space between the knife edge and the valve plate. See picture 3.
If any light can be seen between the two arrows on the picture, the valve
plate is worn.
If any scratches or marks can be felt by running a fingernail over the surface,
the valve plate is worn.
The valve plate on picture 3 is highly damaged.
